Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant cosmetic which is excellent in persistence of fragrance, free of stickiness and excellent in use feeling. More specifically, the present invention relates to a deodorant cosmetic containing two types of fragrances, a fragrance included with a cyclodextrin and a fragrance not included.

[0002]

2. Description of the Related Art Conventionally, sweating from the armpit has been suppressed,
Deodorant cosmetics have been used to prevent the occurrence of armpit odor due to sweat. As such a deodorant cosmetic, an antiperspirant or a bactericide is dispersed in a solid oil or fat base material, and a stick product formed into a stick shape, or an antiperspirant or a bactericide is dissolved or dispersed in a solvent. Roll-on products in which the liquid composition is filled in a roll-on coating container are known. Recently, an aerosol product, which is a combination of a powder base such as talc and a bactericide such as triclosan or an antiperspirant such as aluminum chloride, and a propellant such as LPG, has been developed for its superior usability. It has become widely used for.

[0003] By the way, these deodorant cosmetics are blended with a fragrance in order to enhance the feeling of use and to mask the odor generated in the base material of the cosmetics and underarms. In this case, the fragrance is simply homogeneously mixed with the other ingredients.

However, when the fragrance is simply mixed uniformly as described above, the fragrance volatilizes at a high rate, so that, for example, the fragrance immediately after application to the armpits is good, but the fragrance is lacking in sustainability. is there. For this reason, there has been a problem that the masking effect of the fragrance cannot be obtained particularly when an abnormal odor is generated due to the action of microorganisms after about one hour has passed after sweating. In addition, the typical frequency of use of such deodorant cosmetics is usually every two to three hours at work or commuting in the morning, at break in the morning, at lunchtime, at break in the afternoon, and at home. It is required that the fragrance at the beginning of use lasts for about 2 hours,
As described above, simply mixing the fragrance uniformly does not provide the deodorant cosmetic with a fragrance that sufficiently satisfies such demands.

[0005] Therefore, as a fragrance of Deodorand cosmetics, a fragrance included with cyclodextrin (CD) (hereinafter referred to as CD inclusion fragrance) and a fragrance not included (hereinafter referred to as non-inclusion fragrance). It has been proposed to use two types of fragrances in combination (Japanese Patent Laid-Open No. 8-183719). By using two kinds of fragrances in this way, a desirable fragrance of non-inclusion fragrance can be expected immediately after use of the deodorant cosmetic, and a continuous fragrance of CD inclusion fragrance can be expected.

[0006]

SUMMARY OF THE INVENTION Incidentally, Japanese Patent Application Laid-Open No.
When a CD inclusion flavor and a non-inclusion flavor are used in combination as described in JP-A-183719, for example, when preparing a deodorant cosmetic, it is necessary to maintain the fragrance persistence for about 2 hours. It was necessary to add about 5% to 10% of a CD inclusion flavor.

[0007] However, the CD inclusion flavor is 5% to 10%.
In general, when about% is added, the problem of stickiness does not generally occur, but some users may feel sticky and judge that the feeling of use is unfavorable. For this reason, it has been required to further reduce the stickiness while maintaining the scent persistence at the same level as in the past when the CD inclusion flavoring agent is added.

An object of the present invention is to solve the above-mentioned problems of the prior art, and is a deodorant cosmetic which uses a combination of a CD inclusion flavor and a non-inclusion flavor, and has a good fragrance immediately after use. It is another object of the present invention to provide a deodorant cosmetic which exhibits fragrance continuity for at least about 2 hours, has no stickiness, and is excellent in use feeling.

[0009]

SUMMARY OF THE INVENTION The present inventor has proposed a fragrance to be included in CDs, which is easy to be included in CDs, and generally has a high odor persistence and strong odor. At least one selected from the group consisting of aldehydes having 12 carbon atoms, alcohols having 8 to 12 carbon atoms, ketones having 8 to 12 carbon atoms, and acetate esters of alcohols having 7 to 10 carbon atoms is used as an essential fragrance component. In addition, it has been found that the above-mentioned object can be achieved by setting the selected essential fragrance component in the included fragrance in a predetermined ratio or more, thereby completing the present invention.

That is, the present invention relates to a deodorant cosmetic containing a CD inclusion flavor and a non-inclusion flavor, wherein the fragrance contained in CDs contains aldehydes having 8 to 12 carbon atoms;
At least one fragrance component selected from the group consisting of alcohols having 8 to 12 carbon atoms, ketones having 8 to 12 carbon atoms, and acetic acid esters of alcohols having 7 to 10 carbon atoms is contained in an amount of 15% by weight or more. A deodorant cosmetic is provided.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

In the deodorant cosmetic of the present invention,
A combination of a CD inclusion flavor and a non-inclusion flavor is used. Therefore, immediately after the use of the deodorant cosmetic, the non-inclusion fragrance can emit a good scent. This non-inclusion fragrance gradually weakens its fragrance, but conversely, the CD inclusion fragrance emits fragrance components due to underarm sweat and moisture, and can compensate for the decrease in fragrance of the non-inclusion fragrance . Therefore, it becomes a deodorant cosmetic which is excellent in sustainability of the fragrance. Moreover, as a fragrance to be included in CDs, a specific fragrance component which is easily included in CDs, has excellent fragrance persistence and has a strong odor,
Since it is used in a specific compounding amount or more, the inclusion rate can be increased, and the mixing ratio of the CD inclusion flavor to the deodorant cosmetic can be reduced. Therefore, the stickiness due to CDs can be greatly suppressed and the feeling of use of the deodorant cosmetic can be improved without lowering the persistence of the aroma of the deodorant cosmetic than before.

[0013] In the present invention, aldehydes having 8 to 12 carbon atoms, which are easily included in CDs, have excellent fragrance persistence, and have a strong odor, as described above, are used as fragrances to be included in CDs. Alcohols having 8 to 12 carbons, ketones having 8 to 12 carbons and 7 to 10 carbons
At least one selected from the group consisting of acetic acid esters of alcohols is used as an essential fragrance component. In this case, the content of these essential flavor components in the flavor to be included in the CD is at least 15% by weight or more, preferably 20% by weight or more. If the content is less than 15% by weight, a large amount of CD inclusion flavor must be added to the deodorant cosmetic in order to maintain the desired aroma, resulting in stickiness.

In addition to the essential fragrances described above, the same fragrances as non-inclusional fragrances described later may be used in combination with the fragrances to be included in the CD.

Preferred types of such essential fragrance compounds include terpene compounds, such as terpene aldehydes having 10 carbon atoms (preferably, citral, citronellal, hydroxycitronellal, etc.); C10 terpene alcohols (preferably linalool, geraniol, menthol, citronellol, terpineol, etc.), C10 terpene ketones (preferably mentone, carvone, camphor, etc.) and C10 terpene Acetates of alcohol (preferably linalyl acetate, geranyl acetate, menthanyl acetate, terpinyl acetate, etc.) can be mentioned.

Examples of essential fragrances other than terpene compounds include undecyl aldehyde, vanillin, helional (2-methyl-3- (3,4-methylenedioxyphenyl)) as aldehydes having 8 to 12 carbon atoms. And alcohols having 8 to 12 carbon atoms such as phenylethyl alcohol, phenoxyethyl alcohol, and dimethylbenzylcarbinol; and ketones having 8 to 12 carbon atoms include acetophenone. , Cis jasmon (3-methyl-2-
(Cis-2-penten-1-yl) -2-cyclopenten-1-one) and the like.
Benzyl acetate and the like can be given as examples of the acetic acid esters of alcohols Nos. 10 to 10.

In the present invention, the non-inclusion fragrance which is not included in the CDs is not particularly limited, and a general synthetic fragrance, natural fragrance or compounded fragrance can be used. For example, hydrocarbons having 8 to 12 carbon atoms (for example, limonene, pinene, terpinolene, etc.) can be used. Further, the fragrance used for the CD inclusion fragrance may be used as a non-inclusion fragrance.

The CDs used in the present invention include:

From Table 3, it can be seen that the deodorant cosmetics of Examples 1 to 5 have less stickiness, have a comfortable feeling of use, and emit a high odor that is practically no problem even after 2 hours from immediately after application. I understand.

On the other hand, the cosmetics of Comparative Example 1 were prepared in Examples 1 to 5
The same amount of CD inclusion perfume was used, and as with them, there was no stickiness and a favorable feeling of use was shown. However, despite the use of linalool, a kind of essential fragrance, linalool was added to CDs. Since it contained only 10% by weight of the fragrance to be included, the scent of the fragrance was insufficient after 2 hours.

Since the cosmetic of Comparative Example 2 did not use any essential fragrance at all, the scent of the fragrance was insufficient after 2 hours.

In the cosmetics of Comparative Examples 3 and 4, the amount of CD inclusion flavor used was twice that of Examples 1 to 5, so that the fragrance was sufficient after 2 hours. Stickiness was felt and the feeling of use was insufficient.

Example 6 A deodorant powdered aerosol cosmetic was produced in the same manner as in Example 1, except that 0.7 g of β-CD (manufactured by Saltwater Port Refining Co., Ltd.) was used instead of maltosyl-β-CD. . This cosmetic was excellent in feeling of use without stickiness similarly to the cosmetic of Example 1, and had excellent odor intensity characteristics.

Comparative Example 5 A deodorant powdered aerosol cosmetic was produced in the same manner as in Example 1 except that no non-inclusion fragrance was used. This cosmetic had no stickiness, but did not have a fragrance immediately after application, and had an insufficient feeling of use.

Example 7 A deodorant lotion was produced by using the CD inclusion flavor and the non-inclusion flavor used in Example 5 and uniformly mixing the components shown in Table 4. The obtained lotion was excellent in persistence of fragrance, sticky, and excellent in use feeling.

Except for using the obtained CD inclusion flavor,
A deodorant lotion was prepared in the same manner as in Example 7.
This lotion did not feel sticky like the lotion of Example 7, but was inferior to the lotion of Example 7 in terms of fragrance persistence. The reason is that the content ratio of the essential fragrance component in the present invention in the fragrance formulation used in Comparative Example 6 was about 12% by weight,
This is probably because the value is lower than 15% by weight in the case of D clathrate.

Comparative Example 7 A deodorant lotion was prepared in the same manner as in Example 7, except that the CD inclusion flavor prepared in Comparative Example 6 was used at 5% by weight. This lotion was excellent in persistence of aroma similarly to the lotion of Example 7, but was slightly sticky due to an increase in the CD amount in the lotion.

Example 8 A deodorant lotion was produced by using the CD inclusion flavor and the non-inclusion flavor used in Example 5 and uniformly mixing the components shown in Table 6. The obtained lotion is
It was excellent in persistence of fragrance, non-sticky and excellent in use.

Comparative Example 8 A deodorant lotion was prepared in the same manner as in Example 8 except that the CD clathrate prepared in Comparative Example 6 was used. This lotion did not feel sticky like the lotion of Example 8, but was inferior to the lotion of Example 8 in terms of fragrance persistence. The reason for this is that in the fragrance formulation used in Comparative Example 6, the content ratio of the essential fragrance component referred to in the present invention is about 12% by weight, which is more than 15% by weight in the case of the CD clathrate fragrance used in Example 8. This is probably because of the low value.

Comparative Example 9 A deodorant lotion was prepared in the same manner as in Example 8 except that the CD inclusion flavor prepared in Comparative Example 6 was used at 5% by weight. This lotion was excellent in persistence of aroma similarly to the lotion of Example 8, but was slightly sticky due to an increase in the CD amount in the lotion.

[0062]
